Glutamic acid (Glu or E) is a proteinogenic amino acid. Glutamate, which are what carboxylate anions and salts of glutamic acid are known as, are important neurotransmitters that play a vital role in the long term potention, which is basically an enhancement of the signal transmission between two neurons that happens when both are stimulated synchronously. This is important for both learning and memory. Glutamic acid is involved with the delivery of potassium across the blood-brain barrier and helps with the metabolism of sugars and fats.
Perhaps the most significant benefit of is that it is one of the few nutrients that can cross the blood-brain barrier and is the only nutrient that capable of removing ammonia from the brain; essentially detoxifying ammonia from the brain. Glutamic acid also plays a role with the metabolism of sugars and fats. The prostate gland in men contains glutamic acid and it is thought that it plays a role in healthy prostate function.
Glutamic Acid is found in Meat, Fish, dairy products, eggs, plants high in protein such as beans
